P89LPC980/982/983/985
8-bit microcontroller with accelerated two-clock 80C51 core
7.13 Memory organization
The various P89LPC980/982/983/985 memory spaces are as follows:
DATA
128 bytes of internal data memory space (00H:7FH) accessed via direct or indirect
addressing, using instructions other than MOVX and MOVC. All or part of the Stack
may be in this area.
IDATA
Indirect Data. 256 bytes of internal data memory space (00H:FFH) accessed via
indirect addressing using instructions other than MOVX and MOVC. All or part of the
Stack may be in this area. This area includes the DATA area and the 128 bytes
immediately above it.
SFR
Special Function Registers. Selected CPU registers and peripheral control and status
registers, accessible only via direct addressing.
XDATA
‘External’ Data or Auxiliary RAM. Duplicates the classic 80C51 64 kB memory space
addressed via the MOVX instruction using the DPTR, R0, or R1. All or part of this
space could be implemented on-chip. The P89LPC982 and P89LPC985 have
256 bytes of on-chip XDATA memory, plus extended SFRs located in XDATA.
CODE
64 kB of Code memory space, accessed as part of program execution and via the
MOVC instruction. The P89LPC980/982/983/985 has 4 kB/8 kB of on-chip Code
memory.
7.14 Data RAM arrangement
The 768 bytes of on-chip RAM are organized as shown in Table 8.
7.15 Interrupts
The P89LPC980/982/983/985 uses a four priority level interrupt structure. This allows
great flexibility in controlling the handling of the many interrupt sources. The
P89LPC980/982/983/985 supports 15 interrupt sources: external interrupts 0 and 1,
timers 0 and 1, timer 2/3/4, serial port TX, serial port RX, combined serial port RX/TX,
brownout detect, watchdog/RTC, I2C-bus, keyboard, comparators 1 and 2, SPI, ADC
completion.
Each interrupt source can be individually enabled or disabled by setting or clearing a bit in
the interrupt enable registers IEN0 or IEN1. The IEN0 register also contains a global
disable bit, EA, which disables all interrupts.
